Replace engine oil and filter on the 1972 Ford F-100 with 302ci V8, using 5 quarts of 10W-30 or 10W-40 conventional motor oil.

Warnings

Tools required

Parts

• Spin-on oil filter × 1 — Motorcraft FL-1A or equivalent
• Oil drain plug crush washer × 1 — Use OEM specification

Fluids

• 10W-30 or 10W-40 conventional motor oil — 5 qt

Preparation

1. Park vehicle on level surface and engage parking brake.
2. Allow engine to cool if recently operated.
3. Raise front of vehicle using floor jack and secure on jack stands under frame rails.
4. Verify vehicle stability before working underneath.
5. Locate oil drain plug on passenger side of oil pan and oil filter on driver side of engine block.

Procedure

1. 1

   Drain engine oil
   Position drain pan beneath the oil drain plug on the oil pan (verify plug location on your pan, as it varies by application). Using 9/16" socket, loosen drain plug counterclockwise and remove by hand once loose. Allow oil to drain completely for 5-10 minutes. Inspect drain plug threads for damage.
2. 2

   Install drain plug with new washer
   Thread drain plug into oil pan by hand to avoid cross-threading, then torque to specification using torque wrench. The tapered pipe plug seals via the tapered threads and does not require a washer.
   Torque spec

   Oil Drain Plug35 Nm (26 lb-ft)
3. 3

   Remove old oil filter
   Position drain pan beneath the oil filter, which mounts low on the driver side of the engine block (verify location on your engine). Using oil filter wrench, turn filter counterclockwise to remove. Expect residual oil to drain from filter mount. Wipe mounting surface clean with shop rag and inspect for damage or old gasket material.
4. 4

   Install new oil filter
   Apply thin film of clean engine oil to rubber gasket on new filter. Thread filter onto mounting boss by hand, turning clockwise. Once gasket contacts mounting surface, hand-tighten firmly and then rotate an additional 3/4 turn. Do not use a torque wrench on the spin-on filter; hand-tightening 3/4 turn past gasket contact is the correct installation method for this filter.

   Oil Filter (Spin-On)20 Nm (15 lb-ft)
5. 5

   Fill engine with oil
   Lower vehicle to ground if desired for easier access to valve covers. Remove oil filler cap from driver side valve cover. Using funnel, pour approximately 4 quarts of 10W-30 or 10W-40 conventional motor oil into engine, reserving the remainder for topping off (total capacity approximately 5 quarts with filter). Install filler cap.
6. 6

   Start engine and check for leaks
   Start engine and allow to idle for 30-60 seconds. Monitor oil pressure gauge for normal pressure indication. While engine is running, inspect drain plug and oil filter for leaks. Shut off engine if any leaks are observed and correct before proceeding.
7. 7

   Check oil level and top off
   Shut off engine and wait 2-3 minutes for oil to drain back into pan. Remove dipstick, wipe clean, reinsert fully, then remove and check level. Oil should read at or slightly below FULL mark. Add remaining oil in small increments as needed to bring level to FULL mark. Do not overfill.

Reassembly

1. Ensure oil filler cap is reinstalled securely.
2. Verify no tools or rags were left in engine compartment.
3. Dispose of used oil and filter at appropriate recycling facility.

Verification

• Oil level on dipstick reads at FULL mark when checked on level ground with engine off.
• No oil leaks visible at drain plug or oil filter after test run.
• Oil pressure gauge shows normal pressure at idle and under acceleration.
• Service interval recorded in maintenance log with date and mileage.
